In late 2008 I wrote about my experience using the first generation 80GB Intel X25-M SSD — my first SSD. I had to pay the early adopter tax for that SSD, so it cost me around $700. The speed boost alone justified the price to me. Fast-forward about a year and that SSD stopped working. I’m not quite sure what died — the controller or something else — but I RMA’d it with Intel and they sent me a new, second generation X25-M that week. The second generation (G2) X25-M is based on 34nm fabrication compared to the 50nm first generation. The G2 is also substantially cheaper at roughly $299 and noticeably faster due to a new controller and firmware. Intel still claims the same “up to 250MB/s” sequential read speed and “up to 70MB/s” sequential write speed but the G2 brings improved (2x for 80GB, 2.5x for 160GB version) random 4KB writes.
